We typically use the Amsoil 10w40 Synthetic premium because of it's high zinc content which has additional lubrication properties.
If you plan on racing (people like Captain Insano) you'll want to compensate by using a slightly thicker oil.
All of our "street driven" single turbo cars have used the Amsoil synthetic premium oil, including Shivs.
Hey mike, so what types oil should oil use if I'm plaining on race a lot?
